College spokesman Rich Fujita says initial field testing indicated possible traces of LSD in three loaves of bread found by a student in his vehicle on Monday. The college responded by issuing a warning to students and others not to eat foods of unknown origin.

However, Fujita says on Tuesday that additional testing concluded there was no controlled substance after all.

A student reported find the bread on the passenger seat in his vehicle. Fujita says the student had no idea how the bread got there and contacted campus security.
